This study was to examine the alterations in metabolic parameters, anti-oxidant superoxide dismutase (SOD), inflammatory marker high-sensitivity C-reactive protein (hs-CRP) and microbiota after 24-week risperidone treatment in drug naïve, normal weight, first episode schizophrenia patients; the study further examined the relationship between metabolic changes and changes in microbiota.
The effect of risperidone treatment in patients with schizophrenia varies according to the dopamine receptor genes. This study aimed to evaluate the relationship between genes of the dopamine receptors (D1, D2, and D3) and the effect of risperidone treatment.
Treatment response to antipsychotic drugs is variable and conflicting results have been obtained while studying the influence of DRD2 and HTR2 genetic variants on antipsychotic drug efficacy. To explore further, the present study aimed to assess the influence of DRD2 -141 C Ins/Del, Taq1A and HTR2A -1438 G/A, 102T/C and HTR2C -759 C/T genetic polymorphisms in response to risperidone in patients with schizophrenia. The study was conducted among the n=320 South Indian patients with schizophrenia who received ...
Assessments of the pharmacological profiles of antipsychotic agents have shown that the serotonin receptor family is often involved in their pharmacodynamics. Response to antipsychotic therapy is highly variable, yet prognostic biomarkers are lacking. The aim of the study was to investigate the association of 14 single nucleotide polymorphisms (SNPs) selected from HTR3C, HTR3D, HTR5A and HTR6 with risperidone response in 201 Han Chinese schizophrenia patients. The results showed that the HTR6 rs6699866 was ...
Although currently approved antipsychotics exert efficacy on positive symptoms of schizophrenia, treatments for negative symptoms remain a major unmet need. Post hoc analyses were used to investigate the possible efficacy of cariprazine in patients with moderate/severe negative symptoms of schizophrenia and no predominance of positive symptoms. Data were pooled from 2 randomized, double-blind, placebo- and active-controlled cariprazine studies in patients with acute schizophrenia (NCT00694707, NCT01104766)....
Risperidone, one of the second-generation antipsychotics, can efficiently target dopamine D and serotonin 5-HT receptors. There actually exists significant implication of CYP2D6 genetic polymorphisms on the metabolic kinetics of risperidone, little is known about the extent of CYP2D6 impacting human D2 and 5-HT2 A receptor occupancies as well as the clinical efficacy and efficacy in schizophrenia treatment. Here we assessed the influences of CYP2D6 gene polymorphisms on human target occupancies/clinical o...
Donepezil is the first-line of treatment for Alzheimer's disease (AD), which improves cognitive impairment effectively, but whether it has an impact on cognitive impairment in schizophrenia remains unknown. In this study, we evaluated the effects and mechanisms of donepezil on schizophrenia-like cognitive deficits induced by phencyclidine (PCP). The cognitive deficits model of schizophrenia was established by injecting PCP into mice. Risperidone, an atypical antipsychotic drug, served as positive control dr...
To investigate the clinical effects of aripiprazole on sexual dysfunction induced by amisulpride or risperidone in male patients with schizophrenia.
Preclinical and clinical studies have suggested a beneficial effect of combination treatment with atypical antipsychotic drugs and antidepressants (ADs) in schizophrenia and in drug-resistant depression.
Our ability to predict and prevent homicides committed by individuals with schizophrenia is limited. Cognitive impairments are associated with poorer functional outcome in schizophrenia, possibly also homicide. The aim of the current study was to investigate global and specific cognition among homicide offenders with schizophrenia (HOS).
Patients with schizophrenia commonly suffer from impairments in various aspects of cognition. These deficits were shown to have detrimental effects on daily life functioning and might also impair car driving. This study is the first to examine driving behaviour of patients with schizophrenia using an advanced driving simulator, and to explore the role of cognitive abilities of people with schizophrenia for driving.
Risperidone is applied in oral dosage formulations in the treatment of mental diseases. Current trends point toward parenteral delivery systems based on poly(lactide-co-glycolide), with wafers or rods being the more attractive option than the routinely used intramuscular suspension with microparticles. The aim of our work was to study the utility of solution casting and hot melt extrusion in the formulation of wafers and rods with risperidone based on terpolymers, namely poly(lactide-co-glycolide-co-trimeth...
Schizophrenia is a major psychiatric disorder with complex genetic, environmental, and psychological etiologies. Although DISC1 gene has been shown as a risk factor for schizophrenia in some reports, there is a lack of a consensus. We therefore performed separate meta-analyses aiming to assess the associations between DISC1 SNPs and schizophrenia risk. We found that SNP rs821597 is significantly associated with schizophrenia risk in terms of both allelic and genotypic distribution, while SNP rs821616 is ass...
Aberrant WNT signaling has been implicated in the pathophysiology of schizophrenia. WNT7A, a member of the WNT gene family, is considered a potential candidate of schizophrenia. All exons of WNT7A in 570 schizophrenic patients and 563 controls were sequenced, and protein functional analysis was conducted. Five common variants were identified, but none were noted to be associated with schizophrenia. Nevertheless, nine rare mutations, including one schizophrenia-specific missense mutation (c.305G > A), we...
To compare individuals with and without schizophrenia spectrum disorders (SSD) (schizophrenia, schizoaffective disorder, or psychotic disorder not otherwise specified) who die by suicide.
ECT remains an important, yet underutilized, treatment for schizophrenia. Recent research shows that medication-resistant patients with schizophrenia, including those resistant to clozapine, respond well to ECT augmentation. The purpose of this article is to review recent studies of the use of ECT in the treatment of schizophrenia.
Historically, research investigating neural correlates of mentalizing deficits in schizophrenia has focused on patients who have been ill for several years with lengthy exposure to medication. Little is known about the neural and behavioral presentations of theory-of-mind deficits in schizophrenia, shortly after the first episode of psychosis.
Elderly patients with schizophrenia are a particularly vulnerable group often excluded from clinical trials. Currently there is no evidence-synthesis about the efficacy and safety of antipsychotics in this subgroup. We reviewed all randomized-controlled-trials, about antipsychotics in elderly schizophrenics (last search Dec 12, 2017). Pairwise meta-analyses were conducted. The primary outcome was overall symptoms. Secondary outcomes included positive symptoms, negative symptoms, response, dropouts, quality ...
Insomnia is a common feature of schizophrenia. Although several studies have been published about the influence of certain drugs on schizophrenia patients' sleep, there are no well-grounded recommendations about insomnia treatment in this clinical setting. The present review aimed to identify relevant empirical evidence on available treatments of insomnia in patients with schizophrenia, assessing their safety and efficacy.
To provide quantitative conversions between commonly used scales for the assessment of negative symptoms in schizophrenia.
Individuals with schizophrenia are impaired in their ability to recognize emotions based on vocal cues and these impairments are associated with poor global outcome. Basic perceptual processes, such as auditory pitch processing, are impaired in schizophrenia and contribute to difficulty identifying emotions. However, previous work has focused on a relatively narrow assessment of auditory deficits and their relation to emotion recognition impairment in schizophrenia.
Based on a brief overview of the various aspects of schizophrenia reported by numerous studies, here we hypothesize that schizophrenia may originate (and in part be performed) from visual areas. In other words, it seems that a normal visual system or at least an evanescent visual perception may be an essential prerequisite for the development of schizophrenia as well as of various types of hallucinations. Our study focuses on auditory and visual hallucinations, as they are the most prominent features of sch...
The diagnosis of schizophrenia rests on clinical criteria that cannot be assessed in animal models. Together with absence of a clear underlying pathology and understanding of what causes schizophrenia, this has hindered development of informative animal models. However, recent large-scale genomic studies have identified copy number variants (CNVs) that confer high risk of schizophrenia and have opened a new avenue for generation of relevant animal models. Eight recurrent CNVs have reproducibly been shown to...
Schizophrenia has been characterized as a neurodevelopmental disorder of brain disconnectivity. However, whether disrupted integrity of white matter tracts in schizophrenia can potentially serve as individual discriminative biomarkers remains unclear.
Schizophrenia is a severe psychiatric disorder, and complement 3 (C3) is closely related to schizophrenia. We investigated the association between C3 polymorphisms and schizophrenia in a Northeast Han Chinese population.
